How do you use a bulb thermometer?
Hold the Thermometer at Eye Level. You must hold the thermometer at the end of the stem, not the bulb end. (If you held the bulb end, your body heat could cause the temperature reading to increase if the temperature of your fingers is greater than the temperature shown on the thermometer.)
What does the bulb of the thermometer contains?
mercury
It consists of a bulb at one end followed by a long strip on which the readings are marked. The bulb contains a liquid. The bulb of a clinical thermometer contains mercury.
Why is a bulb of a thermometer made of thin glass?
Glass has a very low coefficient of thermal expansion. This is the reason why thermometer bulb or for a matter of fact entire thermometer is made up of glass. Due to low coefficient of thermal expansion, when the thermometer undergoes a large temperature change it will have minimal change in dimensions.
What is your normal body temp?
98.6°F
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
How does a bulb thermometer work and how does it work?
Bulb Thermometers The bulb thermometer is the common glass thermometer you probably grew up with. The thermometer contains some type of fluid, generally mercury. Bulb thermometers rely on the simple principle that a liquid changes its volume relative to its temperature.
Which is metal is used in the bulb of thermometer?
mercury is the metal used in thermometer. The traditional thermometer is a glass tube with a bulb at one end containing a liquid which expands in a uniform manner with temperature. The tube itself is narrow (capillary) and has calibration markings along it.
Is it possible to calibrate a bulb thermometer?
What you have created is a simple bulb thermometer. And it works pretty well. If you wanted to you could calibrate it, and it would tell you the temperature fairly accurately. This particular thermometer has a few problems, however:
How is wet bulb temperature used in meteorology?
Meteorology – forecasters use wet-bulb temperature to predict rain, snow, or freezing rain. Wet-Bulb Globe Temperature is a kind of an apparent temperature – the temperature perceived by humans – used to estimate the effect of temperature, humidity, wind speed, and sunlight on humans.
